Excellent for recovery Didn't scratch the surface but what I did use worked great. I needed to recover data off a phone with a dead screen and with only a keyboard for input. This was the only app I could find that had a simple enough set up that I could do it unsighted. Pulled my precious stupidly not backed up photos and so happy customer. Many thanks to the author I'll try my best to pay your efforts forward as suggested.
Update: Had unresolvable issue with rsync not parsing whitespace, so switched to a different SSH app. Original review: Outstanding. Truly in the linux spirit of free and good. I came across this in the quest for a 'SSH Server', WITH PUBLIC KEYPAIRING, and I'm still not sure why I overlooked it till now, maybe the icon?... After only been using it for a few hours, I can already see this is the perfect solution for setting up rsync and SSH protected filetransfer/shell connectivity to my devices. Never mind how useful zeroconf and browser-based clipboard read/write and logs are. I even like the documentation :) Thank you very much Mr Lutus!
Almost perfect It works well and includes busybox which is GREAT! The only problem is when i click stop&quit, actually the server process doesnt close... (I have to remove it manually from the recent apps.)
Liked it Very useful for transferring data from computer to phone and vice-versa. One problem is that, it seems that on Marshmallow, "Stop Server and Quit" does not actually stop the server - the app will continue accepting connections/not terminate existing connections.
The only one that works with modern SSH clients. However it has serious issues with user access rights. Currently the server does not allow Public Key encryption. Also any user with the password can log in. Passwords are also visible by people using wireshark, compromising this application's security. So looking for a better alternative.
Excellent - a must-have utility which has saved my bacon more than once. If you're ever in Barcelona, Mr. Lupus, I owe you a couple of pints!
